What's actually causing this
Exterior paint peels when moisture gets beneath the paint film. This happens from inadequate caulking around windows and trim, missing or blocked soffit vents (causing interior moisture to push outward), or applying new paint over a dirty or glossy surface.

Step-by-step fix
-
1
Address the moisture source first
Check caulking around windows, doors, and trim. Ensure gutters are directing water away from the wall. Check that soffit vents are clear.
-
2
Scrape all loose paint
Use a paint scraper to remove all peeling paint. Don't just paint over loose areas — the new paint will peel within months.
-
3
Clean the surface
Wash the entire area with a pressure washer or scrub with a trisodium phosphate (TSP) solution. Let dry fully — at least 24 hours.
-
4
Sand and feather edges
Sand the edges of the scraped areas with 80-grit sandpaper to eliminate hard lines. Smooth bare wood with the direction of the grain.
-
5
Prime and paint
Apply an oil-based or stain-blocking exterior primer to all bare wood. Let cure per the product spec (usually 24 hours). Apply two coats of exterior paint.
